First of all have you made any hardware additions or changes? memory, hard drives new printer? If so un-do what you did!
Next can you get into the machine in safe mode by pressing F8 before the windows logo appears? and then choosing safe mode? If you can check the event log by right clicking my computer, choosing manage and viewing the system and application logs for any recent errors.
I have also seen this problem caused by your only hard drive not connected as a master and configured as a slave.
When did the problems start occuring? Have you done any software updates? If you can get into safemode you can do a windows system restore. If it fails you can attempt to do a system restore from the command prompt in safemode by following these directions:
Drop to a command prompt by doing a run (Windows Key – R)
Type CMD to get your command prompt.
Get to c:\windows\system32\restore anyway you like
and finally launch RSTRUI.exe and you should get the System Restore Wizard</ol>
BobKberg here – another common cause for this type of blue screen are viruses, disk/file system corruption.
To deal with those, I usually take out the hard disk and mount it as an additional drive on a “cleaning machine” and then perform a full backup, CHKDSK and virus scan.
